Auction 10

RGGI Auction 10 was held on December 1, 2010 and monitored by Potomac Economics, an independent monitor of electricity markets retained to evaluate the RGGI CO2 allowance market. Potomac observed the auction and confirmed that there was no material evidence of collusion or manipulation by bidders, and that the vast majority of bids were consistent with competitive expectations.

A total of 49 qualified bidders, listed by name in section 4 below, submitted an Intent to Bid in the auction.

The following statistics summarize the purchases and holdings of allowances by electric generators and their corporate affiliates ("compliance entities") under the RGGI program:

In Auction 10, compliance entities and their affiliates purchased:

97 percent of the current control period allowances sold and

100 percent of the future control period allowances sold.

In the first 10 RGGI auctions, compliance entities and their affiliates purchased:

85 percent of the current control period allowances sold,

96 percent of the future control period allowances sold, and

85 percent of all allowances sold.

Compliance entities and their affiliates will hold 95 percent of the allowances in circulation following the settlement of allowances sold in Auction 10.

3. Dispersion of Bids

Bids were widely dispersed across both compliance entities and non-compliance entities in both the current and future control period offerings.

In the auction for current control period allowances, most of the bidders that submitted a large number of bids (e.g., at least 2 million tons which is 6 percent of the available supply) were compliance entities. Overall, compliance entities accounted for 97 percent of the quantity of bids submitted in the current control period auction.

In the auction for future control period allowances, most of the bidders that submitted a large number of bids (e.g., at least 100,000 tons which is 5 percent of the available supply) were compliance entities. Overall, compliance entities accounted for 100 percent of the quantity of bids submitted in the future control period auction.

The following figure summarizes the quantities of bids submitted in the two auctions by all bidders.
